[FFmpeg-user] Using ffmpeg to send multicast

This ffmpeg-generated stream is played very well by VLC (both Windows
and Linux), but mplayer/FreeBSD somehow cannot play
rtp://188.8.131.52:5000 with the "Stream not seekable!" error. Is it a
limitation of mplayer or is there something wrong with the rtp stream
I am sending?
In Wireshark, it looks like normal, good RTP.
